Dell Constellation ES.2 2 TB SAS drive

This Dell Constellation ES.2 is a new 2 TB internal hard drive spinning at 7200 RPM with a 64 MB buffer. It uses a 3.5 inch SAS 6 Gb/s interface and ships with a PowerEdge server caddy tray. The drive is built for enterprise storage workloads in compatible Dell systems.

Suits PowerEdge server upgrades and replacements

The included caddy fits the listed PowerEdge models including R310, R320, R410, R415, R420, R510, R515, R520, R610, R620, R710, R720, R720xd, T310, T320, T410, T420, T610, T620 and T710. Systems without SAS backplanes or without 3.5 inch drive bays cannot use this drive. Buyers needing larger capacities or different form factors should look at other options.

3.5 inch SAS 6 Gb/s interface decides fit

The single specification that determines compatibility is the 3.5 inch SAS 6 Gb/s interface combined with the supplied PowerEdge caddy. Only servers with matching SAS backplanes and 3.5 inch bays from the supported list will accept this drive directly. Verify your server model and backplane type before ordering.

Questions about this item

How do I install the ST32000645SS into a PowerEdge R720 and which step is often missed?

Slide the drive into the supplied 3.5" SAS caddy until the connector seats firmly, then lock the caddy lever; the step most people miss is fully engaging the lever latch before closing the chassis door.

What maintenance or replacement will the ST32000645SS need after extended use?

The 7200RPM mechanical drive will eventually require replacement when SMART reallocated-sector counts rise or bearing noise appears; no user-serviceable parts exist inside the sealed 3.5" SAS housing.

What limit appears first on the ST32000645SS during sustained heavy writes?

The 6Gb/s SAS interface and 64MB cache saturate before the platters, capping sustained throughput at the interface ceiling during long sequential workloads.
